I think most people will agree that Super Mario Galaxy and Super Mario Galaxy 2 are superb games. As was discussed on the latest episode of RFN, however, there were a handful of missions that undermined an otherwise fantastic experience. I'm of course referring to the infuriating and aptly namely 'Garbage Dumb' levels. These sections of course weren't enough to sink the experience thanks to the overall quality of the games as a whole, but they did stick out like a sore thumb.
Which got me to thinking about the flip side: what examples are there of games which I dislike overall but which have features or qualities that I enjoyed greatly?
Here are a few that came to mind.
Super Paper Mario & Paper Mario: Sticker Star's visual style
While the original Paper Mario and it's immediate sequel The Thousand Year Door tickled me pink, the next two games in the series were largely disappointing, wallowing as they did in inane dialogue and undercooked mechanics; but boy did they look good!
Nightsky's Music
The first few levels of Nightsky are so endearing. The visuals are eye-catching, with delicate acoustic guitar sometimes being accompanied by discordant yet relaxing tones, and the levels (like the orb you control) delicately roll from one into the next. The problem for me was that the game never goes anywhere interesting. It was the equivalent of dropping a marble into a bowl, it's fun the first few times you do it but it gets old quick. The one thing that did not get old, however, was the exceptional music, without which I don't think I would have seen Nightsky through to the end.
Super Smash Bros' everything (except the game) 
When I bought Brawl the day it was release I finally resigned myself to the fact that I will never understand the appeal of Smash Bros' gameplay. I just don't get it. I have no doubt there's a hidden depth and complexity there that goes completely over my head, but to me it just feels...too chaotic?...Mashy even? Is that even a word?
Anyways, what I have always enjoyed about the series has been the 'everything' that Sakurai puts around the game: the trophies, the stickers, the CG cut scenes, and especially the music. Basically, I enjoy the devotion to fan service, even if I don't exactly enjoy the games themselves.
What about you? What the are the things you like about the games you don't?
